Ua lilo nā mea kanu nitrogen maʻemaʻe kiʻekiʻe i mea koʻikoʻi i kekahi mau ʻoihana e like me nā kemika, nā uila, a me nā noi olakino. He mea koʻikoʻi ka Nitrogen i loko o kēia mau ʻoihana a pau, a ʻo kona maʻemaʻe a me kona maikaʻi ke kuleana koʻikoʻi i ka hōʻoia ʻana i ka maikaʻi o ka huahana hope. No laila, ʻo ka hana ʻana i kahi lako nitrogen kiʻekiʻe ka mea nui loa.
ʻO Pressure swing adsorption (PSA) kahi ʻenehana hiki ke hoʻohana ʻia e hoʻomaʻemaʻe i ka nitrogen ma ka wehe ʻana i ka oxygen a me nā mea haumia ʻē aʻe. Hoʻokumu ʻia ka PSA ma ke kumu o ka adsorption kinoea ma kahi mea adsorbent paʻa. Ua koho ʻia ka adsorbent ma muli o kona hiki ke hoʻopili i nā molekele kinoea o ka hoihoi, ʻoiai e ʻae ana i nā kinoea ʻē aʻe e hele.
I loko o kahi mea kanu nitrogen maʻemaʻe kiʻekiʻe, hiki ke hoʻohana ʻia ka ʻenehana PSA e hana i ka nitrogen a i ʻole ka oxygen ma ke kāohi ʻana i ka adsorption a me ka desorption o nā molekele kinoea. ʻO ke kaʻina hana e pili ana i ka hoʻoomi ʻana i ka ea i kahi kaomi i kuhikuhi ʻia a hele i loko o kahi moena o nā mea adsorbent. E hoʻopili ka mea adsorbent i ka oxygen a me nā mea haumia ʻē aʻe, aʻo ka nitrogen e hele i ka moena a hōʻiliʻili ʻia i loko o kahi pahu mālama.
Hiki ke hana hou ʻia ka mea adsorbent ma ka hoʻokuʻu ʻana i ke kaomi, kahi e hoʻoneʻe ai nā molekala kinoea mai ka mea. Hoʻopau ʻia ke kinoea desorbed i waho o ka ʻōnaehana, a mākaukau ka adsorbent e hoʻopili i kekahi pōʻai o nā molekele kinoea.
ʻO kekahi o nā pōmaikaʻi nui o ka hoʻohana ʻana i ka ʻenehana PSA i nā mea kanu nitrogen maʻemaʻe kiʻekiʻe ʻo ia ke kumu kūʻai. ʻOi aku ka maikaʻi o ka ʻenehana PSA a ʻaʻole koi i nā mea paʻakikī a i ʻole nā limahana kūikawā e hana. Eia hou, he haʻahaʻa koina hana, no ka mea, ʻaʻole ia e koi i kekahi kumu o waho o ka ikehu ʻē aʻe ma mua o ka ea paʻa.
ʻO kekahi pōmaikaʻi ʻo kona versatility. Hiki i ka ʻenehana PSA ke hana i ka nitrogen a me ka oxygen, ma muli o ka mea adsorbent i koho ʻia. Hiki ke hoʻohana ʻia ka ea i hoʻonui ʻia i ka oxygen i kekahi mau ʻoihana e like me nā noi lāʻau lapaʻau a me ka welding, kahi e koi ʻia ai kahi kiʻekiʻe o ka oxygen.
Eia nō naʻe, ʻo ka hana ʻana i ka nitrogen maʻemaʻe kiʻekiʻe a i ʻole ka oxygen ma o ka ʻenehana PSA e pono ke koho pono i ka mea adsorbent. Pono ka mea adsorbent i ke koho kiʻekiʻe no nā molekele kinoea o ka hoihoi a pono e kūpono i nā kūlana hana o ka mea kanu nitrogen maʻemaʻe kiʻekiʻe. Hoʻohui ʻia, pono e hoʻonui ʻia ka nui a me ke ʻano o ka mea adsorbent e hōʻemi i ka hāʻule kaomi a hōʻoia i ka adsorption kūpono.
I ka hopena, ʻo ka ʻenehana PSA kahi ala maikaʻi loa a maikaʻi hoʻi no ka hana ʻana i ka nitrogen maʻemaʻe kiʻekiʻe a i ʻole oxygen i nā mea kanu nitrogen maʻemaʻe kiʻekiʻe. Hāʻawi ia i nā pono he nui, me ka versatility a me nā kumukūʻai hana haʻahaʻa. Eia nō naʻe, he mea koʻikoʻi ke koho pono ʻana i ka mea adsorbent e hōʻoia i ka maʻemaʻe a me ka maikaʻi o ka nitrogen a i ʻole oxygen i hana ʻia. Me kāna mau pōmaikaʻi he nui, ʻo ka ʻenehana PSA kahi koho maikaʻi no nā ʻoihana e koi ana i ka lako nitrogen kiʻekiʻe.
